Metso’s new VSI Orange Series Rotor
ENSURES MINIMUM DOWNTIME
O
perational uptime plays a key role in
today’s crushing operations where
maximising productivity and reduc-
ing the cost per ton are paramount. T meet
these challenges, Metso has developed
the Orange Series Rotor for vertical shaft
impact (VSI) crushers. With the new rotors
productive uptime can be increased sub-
stantially through longer parts lifetime and
faster service.
The new Metso Orange series Rotor com-
ponents have been reconfigured with built-
in possibility for easy interchange, thus
maximising wear life. The change-out of
primary components through the service
door has been improved.
With the Orange Rotors, maintenance is
made easy by reducing the total number of
wear parts by 30% and the total number of
components by 25%. This is achieved by
integrating several components and using
less fixing points. Hard-facing during main-
tenance is no longer required.
The increase in wear parts life with these
components is significant. The results of
tests conducted on the new primary com-
ponents in real quarry operations show that
in most cases, there has been an enhanced
wear life which for example has shown a
30-35% increase in tip life.
In quarry operations, the extended lifetime
will provide the operator significantly in-
creased operational time with fewer inter-
vals between wear parts changes.
In tip and cavity wear plates replacement,
the actual servicing time can be cut by
more than half, due to simplified retaining
bar fixing.
The Orange Series Rotor was designed with
the busy operators of the older model of
Barmac VSI crushers in mind. The Orange
Series Rotor can be fitted, without any
modifications to all VSI models that accept
the following rotors: 690 DTR, 840 DTR,
and 990 DTR.
